Depth-dependent varation in soft-bottom fauna [PDF]

open access: yes, 1996
Depth is an important variable influencing soft-bottom-fauna communities. Lowest diversities were found at depths shallower than 40 m, probably due to stronger fluctuations in environmental factors. Maximum diversities were found at 65-115 m depth.
